CuI/L5 (N,N'-dimethylethylenediamine) proves to be an efficient catalyst system for the amination of arylhalides with guanidines. The same catalyst system is then successfully applied to the one-step synthesis of 1-H-2-amino-benzimidazoles through tandem aminations of 1,2-dihaloarenes in modest yields. This methodology

Most inanimate systems are build of closed-shell molecules in which electrons lack excitability and mobility. These electrons can be rendered reactive and mobile by taking out some of them, desaturating the system electronically. Single electrons can be taken out of
